A universal system reduces the confusion when different systems of measurement are used and makes it easy to compare measurements taken by different persons.
Here’s a real-world example of the confusion that can occur.
In 1983 an Air Canada Boeing 767 temporarily had no working fuel gauges, so the ground crew resorted to calculating the 767's fuel load by hand. They used a procedure similar to calculating the volume of oil in a car by taking a dipstick reading. This gave them the volume. But airlines measure the amount of fuel by mass. They needed the density of jet fuel to make the proper calculations.
The ground crew used 1.77 lb/L as the density, as they had on all other planes in the fleet. But the brand new 767 was metric and used 0.8 kg/L as the density. The plane had only about half the fuel the crew believed they had. The plane ran out of fuel and sank too fast to reach its destination. Only a nearby abandoned Air Force base was a possible landing spot. The crew made a remarkable dead-stick glider landing. There were only minor injuries to the passengers as they used the emergency exits on the plane.
Answer:
The correct answer is Broca's area or Wernicke's area.
Explanation:
Aphasia refers to a language disorder, which arises due to the destruction of the parts of the brain, which are accountable for language. Aphasia generally causes due to the destruction of Wernicke's area or Broca's area. For the majority of the individuals, these are the sections of the brain's left hemisphere.
The condition known as aphasia generally takes place suddenly, usually as the outcome of a head injury or stroke, however, it can also arise gradually, in the individuals suffering from a brain tumor. The disorder hampers both the comprehension and expression of language and at the same time the tendency to read and write.
Answer:
D. The insect develops legs in other parts of its body.
Explanation:
HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In <em>Drosophila</em>, it has been shown that different segments of the leg regulate their size in response to Ubx expression.
